GeForce GTX 275 vs GeForce GTX Titan Black

Intro

Compare that to the GeForce GTX Titan Black, which makes use of a 28 nm design. nVidia has clocked the core speed at 889 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this particular model. It features 2880 SPUs along with 240 Texture Address Units and 48 Rasterization Operator Units.

GeForce GTX 275		127008 MB/sec
	Difference: 208992 (165%)

Texel Rate

The GeForce GTX Titan Black should be quite a bit (more or less 321%) faster with regards to texture filtering than the GeForce GTX 275. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 162720 (321%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan Black is the winner, by a large margin. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 24948 (141%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
